Patent abstract
A set of local noise variation values characterizing local noise levels in the input image is calculated. Local contrast enhancement is performed on image forming element values derived from the input image to produce a contrast enhanced image. Values of local noise amplification caused by the local contrast enhancement are ascertained. Noise in the contrast enhanced image is reduced based on the set of local noise variation values and the local noise amplification values.
